"Why, indeed, unless you wished to possess yourself of something in the old room?"

"Again I fail to understand," says Paul; but his very lips grow livid. "Perhaps for the second time, and with the same delicacy you used at first, you will condescend to explain."

"Is it necessary?" says Geoffrey, very insolently in his turn. "I think not. By the by, is it your usual practice to prowl round people's houses at two o'clock in the morning? I thought all such festive habits were confined to burglars, and blackguards of that order."

"We are none of us infallible," says Rodney, in a curious tone, and speaking as if with difficulty. "You see, even you erred. Though I am neither burglar nor blackguard, I, too enjoy a walk at midnight."

"Liar!" says Geoffrey between his teeth, his eyes fixed with deadly hatred upon his cousin. "Liar—and thief!" He goes a few steps nearer him, and then waits.

"Thief!" echoes Paul in a terrible tone. His whole face quivers, A murderous light creeps into his eyes.

Mona, seeing it, moves away from Geoffrey, and, going stealthily up to the table, lays her hand upon the pistol, that is still lying where last she left it. With a quick gesture, and unseen she covers it with a paper, and then turns her attention once more upon the two men.

"Ay, thief!" repeats Geoffrey, in a voice low but fierce, "It was not without a purpose you entered this house to-night, alone and uninvited. Tell your story to any one foolish enough to believe you. I do not. What did you hope to find? What help towards the gaining of your unlawful cause?"

"Thief!" interrupts Rodney, repeating the vile word again, as though deaf to everything but this degrading accusation. Then there is a faint pause, and then——

Mona never afterwards could say which man was the first to make the attack, but in a second they are locked in each other's arms in a deadly embrace. A desire to cry aloud, to summon help, takes hold of her, but she beats it down, some inward feeling, clear, yet undefined, telling her that publicity on such a matter as this will be eminently undesirable.
